The book provides a comprehensive overview of current knowledge about "wattles", a large clade of over 1000 species of trees and shrubs in the genus Acacia, most of which are native to Australia. It examines the biology, ecology, evolution, and biogeography of wattles in their native ranges, including the evolutionary forces that have driven past speciation and adaptation to diverse environments, the conservation status, uses and human perceptions of these species. It considers the different histories of the introductions and proliferation of wattles as alien species in different parts of the world since c. 1850 (the Anthropocene), situated within relevant political, socio-economic and scientific contexts, together with an analysis of how awareness of their impacts as invasive species has changed over time. Differences in the dynamics and trends associated with the introduction, naturalization and invasion of wattles in different parts of the world are reviewed. The book also synthesizes the global distribution of wattles using diverse data sources, alongside trends, patterns and projections of global uses of wattles. It discusses the genetics, biotic interactions, and ecological, economic and social impacts of invasive wattles. This book is aimed at academics and students in the field of ecology, and at managers of natural and anthropic ecosystems, policy-makers and regulators, and the general public interested in biology and environmental science.
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
Biosecurity: A Systems Perspective provides an overview of biosecurity as a system of related components, actors, and risks. This book—directed to the biosecurity practitioner, generalist scientist, and student—introduces overall features of the biosecurity system while walking the reader through the most up-to-date research on each step of the continuum (i.e. pre-border, border, and post-border activities). This book, which explicitly incorporates economic and social dimensions as well as varied decision-making contexts, paves the way for a more systemic approach to biosecurity risk management. The work spans statistics, ecology, mathematics, economics, veterinary science, human medicine, and sociology, involving collaborators across government, academia, and the private sector. This book uses a broad definition of biosecurity, rather than solely focusing on plant health, animal health, security, or one step of the biosecurity system (e.g. surveillance). As such, this book is a one-stop shop for readers interested in all aspects of biosecurity. The content and language are accessible to a wide range of audiences, including generalist scientists, biosecurity practitioners, and graduate students. More complex content is introduced in standalone boxes or chapters. The book follows a clear, simple structure within and among chapters (i.e. following the structure of the biosecurity system), making it a preferred option for graduate students. This book introduces novel cross-cutting themes, such as the importance of economic efficiency and institutional and social factors, going beyond the traditional science-based approach to biosecurity. Written in partnership with government agency practitioners, this book uses on-the-ground case studies to demonstrate how biosecurity principles are applied in practice. The book addresses challenges common to regulators in general, namely efficient regulation in uncertain and rapidly changing environments with multiple stakeholders who have—at times—conflicting priorities.

This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
Humans have moved organisms around the world for centuries but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing, and proposing a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It discusses not only key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analyzing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management.
This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. “This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action”. Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. "This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world". Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK
There are many books on aspects of plant invasions, but none that focus on the key role of species interactions in mediating invasions. This book reviews exciting new findings and explores how new methods and tools are shedding new light on crucial processes in plant invasions. This book will be of interest to academics and students of ecology, researchers engaged in developing management solutions, scientific managers of natural ecosystems, and policy-makers.
"Case studies of the effects of human dispersal of organisms on other organisms and the attitudes of individuals, groups and agencies toward the phenomina. The auther investigates whether introductions of species into new regions actually cause harm, and that damage blamed on excotics may be a result of industrialisation. This and the psycology of racism and xenophobia that prevail in nativism are also explored."
There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research.
